'This invention relates to the manufacture of match boX shells in machines of the kind in which box veneer lengths and, paper are wrapped around a continuously rotating 5 block. In machines of this kind it is wellknown to feed the strip of paper, after paste has been applied thereto, immediately below the veneer supplying device so that the fore end of the strip of paper can be lifted up do against and attached tothe last broad side of the length of veneer, causing thelatter during its wrapping around the block to take the paper with it so that no special feeding device for the paper is required. By means of rollers or cams the paper is pressed against the veneer so that a smooth surface will result. In hitherto known machines operating according to this method the box cannot be completed in this operative position and pushed to the side in ashorter time than what corresponds to about two revolutions of the block and, as a result, supplying of a length of veneer can only take place one time for every second revolution of the blockshaft. The present invention has for its object to increase the output of such machines by wrapping the length of veneeraround the block in a first operative position and moving it along the block to a second operative position for 0 further operation before the completion of one revolution of the block, thus allowing a fresh length of veneer te be supplied to the said first operative position for each revolution of the block.

One embodiment of a machine operating in the manner above indicated is illustrated in the drawings in which, Fig. 1 is a front view of the machine, Fig.2 is a section on the line II-II in Fig. 1, and Fig. 3 is an end view of the machine as seen from the right in Fig. 1.

With reference to the drawings, the numeral 1 indicates the base plate of the machine and 2 is a bearing frame resting on said base plate and in which the main shaft 3 of the machine and the block shaftt are mounted parallel to each other. The other bearings of V saidshafts are not shown for the sake of clearness. The block shaft is driven from the main shaft by means of toothed gearing 5, 6 the ratio of gearing of which is equal to 1: 1, and both shafts rotate, as a result, at the same rate.- Secured to the main shaft are a number of cam disks for various purposes which should be hereinafter more nearly described.

The block shaft 4 is shaped as a block 7 at 1 one end, said block having a cross section whichcorresponds to the boX shape desired. The block 7 is provded with a groove 8 opening in one of the sides of the blockto receive a length of veneer 11 supplied from a reservoir 9 by means of a reciprocating slide 10. In order to effect the reciprocating movement of the slide 10 the main shaft 3 carries a cam disk 12 acting on a bell crank lever. 18 pivotally mounted at 14 and carrying a roller 15 at one end which engages with the cam disk 12, whereas the opposite end of the lever '13 is connected by means of a link 16 to'a lever 17 pivotedat one end about a shaft 18. The opposite endof said lever 17 is connected by .alink 19.tothe slide 10. In order to maintainthe roller 15 in constant engagement with the cam disk 12 the bell crank lever 13 is acted on by a-spring 20. The cam disk 12 is of such ashape as to cause the slide 10 to move one time to and fro for each revolution of the main shaft and supply a length of veneer 11 to the groove 8 for each revolution of the .block shaft 4. The length of veneer will be moved by the rotary block in the direction indicated by the arrow and be wrapped around the block. r 1

Before thelength of veneer, while in this first operative position, has rotated with the block a complete revolution it will be dis placed along the block to a second operative position by. means of two blade springs 21 rotating with the block which are attached to a sleeve 22 slidably mounted on the block shaft 4. Said displacement is effected by means of a lever 23 pivoted at 24 and carrying a roller 25 sliding in a slot of a cam slot disk 26 secured to the main shaft 3.

While the length of veneer is in this second operative position, a strip of paper indicated by the dotted line 60 in Fig. 3 is moved forward to be wrapped around the veneer. Said strip of paper is unrolled from a reel (not shown) and passes below a paste con tainer of any appropriate design. The fore end of said strip is then attached to the ve neer by means of a smoothing roller 27 pressing the pasted paper against the veneer. Said roller 27 is carried at one end of a lever 28 secured to a shaft 29 mounted in two bearings one of which only is shown in the drawings at 30 in Fig. 1. Secured to the said shaft 29 is also a lever 31 carrying a roller 32 in engagement with a cam disk 33 on the main shaft 3. The smoothing roller 27 will hold the paper pressed against the veneer under the action of a spring34 until a little flap only of the paper remains. The roller is then lowered to the position shown in Fig. 2 due tothe shape of the cam disk 33, whereuponthe box, which is now almost ready is displaced to a third operative position and at the same time a length of veneer will be displaced from the first to the second operative position.

- The feeding of the paper to a position right opposite the second operative position is'efl'ected by means of a plate 35 against which the paper is pressed by a roller 36. Said plate 35 is mounted on a lever 37 and said roller 36 is mounted on a lever 38, and both of said levers are pivotally mounted on a common shaft 39. The lever 37 bears with a roller against a cam disk 40 carried by the main shaft, whereas the lever 38 bears with a roller against a cam disk 41 on the mainshaft. Said rollers are held in engagement with the cam disks due to the action of two springs 42 and 43,. respectively. The cam disks are of such a design and so adjustedfelativelyto each other as to cause the roller '36 to press the paper against the plate 35 duringthe forward movement of the and'45 movable towards and away from each otherwhich are carried by two arms 48 and 49, respectively, secured to the-shafts 46 and 47,'respectively. Said'shafts 46, 47 are me- .chanically connected to each other at 50 by "means of small toothed segments so that a rotation of oneshaft will'be positively trans- 66 'mitted tothe other. In order to effecflsuch a rotation a lever 51 is provided which is attached to the shaft 47 and carries a roller which is held in engagement with a cam disk 52 on the main shaft under the action of a spring 53. When said roller passes a recess of the cam disk 52 the knives 44, 45 will, therefore, be caused to move against each other to sever the paper, as will readily appear from Fig. 3.

Should the paper, as hereinbefore assumed, not be completely smoothed in the second operative position but will be moved to the third operative position before the completion of the smoothing operation simultaneously with the displacement of the succeeding length of veneer to the second position by the springs 21, then the smoothing of the last flap of the paper may be effected by means of a separate roller 54. Said roller is mounted at one end of a bell crank lever 55 pivotally mounted on the shaft 56 and the other end of which carries a cam follower engaging a cam disk 57 on the main shaft. Said cam :follower is held depressed against the cam disk due to the action of a spring 58 attached to the bell crank lever 55. The smoothing roller 54 is held lifted out of contact with the box during the main part of the revolution but, when the cam follower of thelever ,55 passes a recess of the cam disk 57, theroller 54 will be moved into engagement with the boxdue to the action of spring 58 to smooth the last flap of paper, whereupon the box is ready to be removed from theblock. 7

Because of thefact that the slide 10 which operates to supply the lengths of veneer to the block 7 has to perform a reciprocating movement for each revolution of the block shaft insteadof performing such a movement for every second revolution only, as was hitherto the :practice, the operation of the machine would-be more smooth if the length of stroke -of the slide could be shortened. Thi-sobjec't can, in fact, be obtained by designing the'sl'ide not asshown in Fig. 2, that is to-s'a'y, with'a single shoulder for the length of veneer to be fed, but with, for instance, two shoulders situated behind each other at a distance-from each other which corresponds to half thelengt-h of the veneer. It will be seenthat in such case twolengths of veneer maybe supplied at the sametimeinhalf overlapping relatively to each other, and each length of veneer will, thus, be supplied in two stages, whereby the length of stroke of .the slide will be but half as great as before.

When the lowermost length of veneer begins to-rotate with the block,the length of veneer following-next which rests immediately upon that under feeding and hasbeen moved half of its path will be prevented from further movement by any appropriate stopping "means.

WVhile "I have hereinbefore describedv a special embodiment of the invention it is to be noted that many modifications may be made within the scope and idea of the invention. For instance, a separate feeding device may be dispensed with, if the paper be attached to the veneer in the first operative position and be displaced together with the veneer before the completion of one revolution to the second operative position to be there wrapped around the veneer.

What I claim is 1. In a machine for manufacturing match box shells the combination with a rotary block to receive lengths of veneer to be wrapped around said block to form the shells of means to continuously rotate said block, and means to supply one length of veneer to a first position on the block for each revolution thereof.

2. In a machine for manufacturing match box shells the combination with a rotary block to receive lengths of veneer to be wrapped around said block to form the shells of means to supply one length of veneer to a first position on the block for each revolution thereof, and separate means to supply a strip of paper to the lengths of veneer in a second position on the block.

3. In a machine for manufacturing match box shells the combination with a rotary block to receive lengths of veneer to be wrapped around said block to form the shells of means to supply one length of veneer to a first position on the block for each revolution thereof, means to displace each length of veener to a second position on the block before the completion of one revolution of the block after the supplying of the veneer to said first position, and means to supply a strip of paper to be wrapped around the lengths of veneer in said second position.

4. In a. machine for manufacturing match box shells, the combination with a rotary block to receive lengths of veneer to be Wrapped therearound due to the rotation of the block, of means to supply one length of veneer at a time to a certain portion of the block, means to displace each such length of veneer to another portion of the rotating block before the completion of the wrapping of said length of veneer around the block, so as to allow a fresh length of veneer to be supplied to said block and have its wrapping initiated there during the completion of the wrapping of said first-mentioned veneer and means to supply a strip of paper to said displaced length of veneer to be wrapped therearound in said displaced position.

5. In a machine for manufacturing match box shells, the combination with a rotary block to receive lengths of veneer to be wrapped therearound due to the rotation of the block, of means to supply one length of veneer at a time to a certain portion of the block, means to displace each such length of veneer to another portion of the rotating block before the completion of the wrapping of said length of veneer around the block, so as to allow a fresh length of veneer to be supplied to said block and have its wrapping initiated there during the completion of the wrapping of the said first-mentioned veneer, means to supply a strip of paper to said displaced length of veneer to be wrapped therearound in said dis laced position, and means to displace said ast mentioned length of veneer with the strip of paper to a third position on the block to have the wrapping of the paper completed there.

In testimony whereof I have signed my name.
